A bill to amend 1965 PA 290, entitled
"Boiler act of 1965,"

176.
THE PEOPLE OF THE STATE OF MICHIGAN ENACT:
1 Sec. 7a. (1) Antique
Except as otherwise provided in this
2 section, antique traction and historical steam boilers preserved,
3 restored, or maintained for hobby or demonstration use shall
4 comply with the rules promulgated by the board and shall be
5 inspected once every 3 years. An owner of an antique traction
6 steam boiler may request an inspection more often than every 3
7 years. Antique traction and historical steam boilers used for
8 commercial purposes shall be inspected annually. If the
9 inspection is made by a
deputy inspector, the fee shall be
10 $25.00 is $45.00. Fees established in this section shall
are
1 not be subject
to change by rule. A certificate of inspection
2 shall be issued by the
department of labor consumer and
3 industry services upon compliance with the applicable rules.
4 (2) This act shall
does not apply to miniature steam or
5 engines, marine engines, or miniature railroad engines used as a
6 hobby and for private use only.
7 (3) The department of consumer and industry services shall
8 not prohibit the public operation of a historical steam boiler by
9 an operator certified by the Michigan historical steam engine
10 association or other similar organization acceptable to the
11 department of consumer and industry services so long as the
12 operator provides proof acceptable to the department of consumer
13 and industry services of both of the following:
14 (a) At least 100 hours of actual operating experience or
15 training in the operation and care of historical antique traction
16 steam boilers.
17 (b) Successful completion of a course designed for training
18 historical boiler operators and the passing of a written or
19 verbal examination, with a score of 70% proficiency, that the
20 department of consumer and industry services, with the advice of
21 the Michigan historical steam engine association, determines
22 sufficient to test the knowledge and competency for the safe
23 operation of historical boilers.
24 (4) The standards of the Michigan historical steam engine
25 association are hereby incorporated by reference as those
26 standards exist on the effective date of the amendatory act that
27 added this subsection. The department of consumer and industry
1 services shall accept proof of certification supplied by the
2 operator that is subject to verification by the certifying
3 organization.
4 (5) The inspection conducted by the department of consumer
5 and industry services shall comply with the following conditions
6 and be conducted under the following circumstances:
7 (a) The owner or operator shall prepare the boiler for a
8 hydrostatic test at least equal to the maximum allowable working
9 pressure and up to 1.25 times the maximum allowable working
10 pressure with water temperature between 60 degrees Fahrenheit and
11 120 degrees Fahrenheit.
12 (b) The inspector shall provide and use a certified
13 calibrated pressure test gauge. The maximum allowable operating
14 pressure shall not exceed the original manufacturer's
15 recommendation for both lap seam and butt strap seam barrel
16 construction.
17 (6) After the completion of the hydrostatic test, the
18 department of consumer and industry services may inspect the
19 boiler for an internal visual inspection of the crownsheet,
20 fluesheets, sidesheets, mudleg, and staybolt. Under those
21 circumstances, the operator shall prepare the boiler for that
22 internal inspection. The department of consumer and industry
23 services shall not require an ultrasonic test.
24 (7) Each boiler regulated under this section shall have the
25 following safety devices:
26 (a) Pressure relief valve, subject to the following
27 conditions:
1 (i) No valve of any type shall be placed between the boiler
2 and the pressure relief valve, and no valve of any type shall be
3 placed in or on the outlet of the pressure relief valve.
4 (ii) The piping between the boiler and the pressure relief
5 valve shall be at least as large as the pressure relief valve
6 inlet diameter and as short as practical.
7 (iii) No reduction in pipe diameter is allowed at the
8 pressure relief valve outlet.
9 (iv) The required pressure relief valve capacity in lbs./hr
10 shall be calculated by the boiler heating surface area above the
11 grates. The minimum lbs. steam/hr per square foot of heating
12 surface shall be 5.
13 (b) Pressure gauge, subject to the following conditions:
14 (i) The pressure gauge shall be operational and proven
15 accurate within 5 psi at the time of inspection.
16 (ii) The pressure gauge shall have a range at least 1.5 times
17 the MAWP.
18 (iii) The pressure gauge shall have a siphon or water seal
19 installed between the pressure gauge and the boiler and shall be
20 as short as practical.
21 (iv) If a valve is installed between the pressure gauge and
22 the boiler, the valve shall indicate the open position or be
23 wired open.
24 (c) Water gauge glass, subject to the following conditions:
25 (i) The gauge glass shall indicate the minimum safe operating
26 water level and be fully operational with working shut-offs.
27 (ii) The gauge glass shall have a drain valve or petcock that
1 is fully operational.
2 (iii) The gauge glass shall be fitted with 2 external guard
3 rods or an equivalent to protect the glass.
4 (d) Try cocks, subject to the following conditions:
5 (i) Try cocks shall be fully operational.
6 (ii) Try cocks shall be correctly located in reference to the

15 fire area more than 1 inch.
16 (v) At the discretion of the field inspector, the fusible
17 plug will be removed at every fourth inspection to observe the
18 ASME marking on filler material in order to inspect the condition
19 of the threads in crown sheet and fusible plug and to remove any
20 accumulation of scale.
21 (vi) Fusible plugs shall not be refilled.
22 (f) Piping and fittings, subject to the following
23 conditions:
24 (i) All steam piping components shall be used in the manner
25 for which they were designed and shall not exceed the
26 manufacturer's pressure rating.
27 (ii) Standard schedule 80 black pipe shall be used below the
